- **Features**:
  - Filament Section components for collapsible groups
  - First group expanded by default
  - Setting rows with labels, formatted values, help text
  - Alpine.js copy buttons with clipboard API
  - Client-side search filtering

SettingsCatalogDefinitionResolver
    ↓ (resolves definitions)
PolicyNormalizer
    ↓ (groups & formats)
PolicyResource (Filament)
    ↓ (renders)

    ↓ (store)
Database + Memory
    ↓ (fallback on Graph failure)
Prettified Definition ID
```

### UI Flow

```
Policy View (Filament)
    ↓
Tabs: Settings | JSON
    ↓ (Settings tab)
Check metadata.definitions_cached
    ↓ (true)
settings_grouped ViewEntry
    ↓
normalizeSettingsCatalogGrouped()
    ↓
Blade Component
    ↓
Accordion Groups (Filament Sections)
    ↓
Setting Rows (label, value, help text, copy button)
```

## Next Steps (Priority Order)

### Immediate (Phase 6 - Manual Verification)

1. **Open Policy View** (5 min)
   - Navigate to `/admin/policies/{id}` for Settings Catalog policy
   - Verify page loads without errors
   - Check browser console for JavaScript errors

2. **Verify Tabs & Accordion** (5 min)
   - Confirm "Settings" and "JSON" tabs visible
   - Click Settings tab, verify accordion renders
   - Verify groups collapsible (first expanded by default)
   - Click JSON tab, verify snapshot renders with copy button

3. **Verify Display & Formatting** (5 min)
   - Check setting labels show display names (not `device_vendor_msft_...`)
   - Verify bool values show as "Enabled"/"Disabled" badges (green/gray)
   - Verify int values formatted with separators (e.g., "1,000")
   - Verify long strings truncated with "..." and copy button

4. **Test Search & Fallback** (5 min)
   - Type in search box (if visible), verify filtering works
   - Test copy buttons (long values)
   - Find policy WITHOUT cached definitions
   - Verify fallback message: "Definitions not yet cached..."
   - Verify JSON tab still accessible

**Total Estimated Time**: ~20 minutes

### Short-Term (Phase 7 - Unit Tests)

1. **Create Unit Tests** (2-3 hours)
   - `tests/Unit/SettingsCatalogDefinitionResolverTest.php`
     - Test `resolve()` with batch IDs
     - Test memory cache hit
     - Test database cache hit
     - Test Graph API fetch
     - Test fallback prettification
     - Test non-blocking warmCache()
   - `tests/Unit/PolicyNormalizerSettingsCatalogTest.php`
     - Test `normalizeSettingsCatalogGrouped()` output structure
     - Test value formatting (bool, int, string, choice)
     - Test grouping by categoryId
     - Test fallback grouping by definition ID segments
     - Test recursive definition ID extraction

2. **Create Feature Tests** (2 hours)
   - `tests/Feature/Filament/PolicyViewSettingsCatalogReadableTest.php`
     - Test Settings Catalog policy view shows tabs
     - Test Settings tab shows display names (not definition IDs)
     - Test values formatted correctly (badges, numbers, truncation)
     - Test search filters settings
     - Test fallback message when definitions not cached
     - Test JSON tab still accessible

3. **Run Test Suite** (15 min)
   - `./vendor/bin/sail artisan test --filter=SettingsCatalog`
   - Fix any failures
   - Verify all tests pass

**Total Estimated Time**: ~5 hours

### Medium-Term (Performance & Polish)

1. **Performance Testing** (1 hour)
   - Create test policy with 200+ settings
   - Measure render time (target: <2s)
   - Measure definition resolution time (target: <500ms for 50 cached)
   - Profile with Laravel Telescope or Debugbar

2. **Manual QA Walkthrough** (1 hour)
   - Test all user stories (US-UI-04, US-UI-05, US-UI-06)
   - Verify all success criteria (SC-001 to SC-010)
   - Test dark mode toggle
   - Test with different policy types
   - Document any issues or enhancements

**Total Estimated Time**: ~2 hours

## Risk Assessment

### ✅ Mitigated Risks

- **Graph API Rate Limiting**: Non-blocking cache warming prevents snapshot save failures
- **Definition Schema Changes**: Raw JSONB storage allows future parsing updates
- **Large Policy Rendering**: Accordion lazy-loading via Filament Sections
- **Missing Definitions**: Multi-layer fallback (prettified IDs → warning badges → info messages)

### ⚠️ Outstanding Risks

- **Performance with 500+ Settings**: Not tested yet (Phase 7, T042)
- **Graph API Downtime**: Cache helps, but first sync may fail (acceptable trade-off)
- **Browser Compatibility**: Alpine.js clipboard API requires HTTPS (Dokploy provides SSL)

### ℹ️ Known Limitations

- **Search**: Client-side only (Blade-level filtering), no debouncing for large policies
- **Value Expansion**: Long strings truncated, no inline expansion (copy button only)
- **Nested Groups**: Flattened in UI, hierarchy not visually preserved

---

## Constitution Compliance

### ✅ Safety-First
- Read-only feature, no edit capabilities
- Graceful degradation at every layer
- Non-blocking operations (warmCache)

### ✅ Immutable Versioning
- Snapshot enrichment adds metadata only
- No modification of existing snapshot data
- Definition cache separate from policy snapshots

### ✅ Defensive Restore
- Not applicable (read-only feature)

### ✅ Auditability
- Raw JSON still accessible via JSON tab
- Definition resolution logged via Laravel Log
- Graph API calls auditable via GraphLogger

### ✅ Tenant-Aware
- Resolver respects tenant scoping via GraphClient
- Definitions scoped per tenant (via Graph API calls)

### ✅ Graph Abstraction
- Uses existing GraphClientInterface (no direct MS Graph SDK calls)
- Follows existing abstraction patterns

### ✅ Spec-Driven
- Full spec + plan + tasks before implementation
- FR→Task traceability maintained
- Implementation notes added to tasks.md

---

## Deployment Readiness

### ✅ Local Development (Laravel Sail)
- [X] Database migration applied
- [X] Services registered in container
- [X] Caches cleared
- [X] Code formatted with Pint
- [X] Table exists with data ready for seeding

### ⏳ Staging Deployment (Dokploy)
- [ ] Run migrations: `php artisan migrate`
- [ ] Clear caches: `php artisan optimize:clear`
- [ ] Verify environment variables (none required for Feature 003)
- [ ] Test with real Intune tenant data
- [ ] Monitor Graph API rate limits

### ⏳ Production Deployment (Dokploy)
- [ ] Complete staging validation
- [ ] Feature flag enabled (if applicable)
- [ ] Monitor performance metrics
- [ ] Document rollback plan (drop table, revert code)

---

## Support Information

### Troubleshooting Guide

**Issue**: Settings tab shows raw definition IDs instead of display names
- **Cause**: Definitions not cached yet
- **Solution**: Wait for next policy sync (SyncPoliciesJob) or manually trigger sync

**Issue**: Accordion doesn't render, blank Settings tab
- **Cause**: JavaScript error in Blade component
- **Solution**: Check browser console for errors, verify Alpine.js loaded

**Issue**: "Definitions not cached" message persists
- **Cause**: Graph API call failed during snapshot
- **Solution**: Check logs for Graph API errors, verify permissions for `/deviceManagement/configurationSettings` endpoint

**Issue**: Performance slow with large policies
- **Cause**: Too many settings rendered at once
- **Solution**: Consider pagination or virtual scrolling (future enhancement)

### Maintenance Tasks

- **Cache Clearing**: Run `php artisan cache:clear` if definitions stale
- **Database Cleanup**: Run `SettingsCatalogDefinition::where('updated_at', '<', now()->subDays(30))->delete()` to prune old definitions
- **Performance Monitoring**: Watch `policy_view` page load times in Telescope

- ✅ Database schema + model
- ✅ Definition resolver with 3-tier caching
- ✅ Snapshot enrichment with cache warming
- ✅ Normalizer with grouping/formatting
- ✅ UI with accordion, search, and fallback

Navigate to Policy View and verify all features work as expected before proceeding to Phase 7 testing.

**Estimated Remaining Work**: ~7 hours
- Phase 6: ~20 min
- Phase 7: ~5-7 hours (tests + QA)

**Feature Delivery Target**: Ready for staging deployment after Phase 7 completion.
